I was reading some things about Qigong. Has anyone tried it before and what was your experience like?

It's basically the name for various Chinese systems of meditation and energy cultivation (qi). I've seen you post regarding schizophrenia if this is what you have then I would suggest against you doing qigong. Qigong is bad for mental disorders simply because it is a very introspective practice and can lead to various problems if your mind is in disarray. If you decide to do this make sure you learn qigong from a qualified instructor. Best bet is to see a chinese medical practitioner and ask for referals at the same time while fully disclosing to them your health issues.
